Our group excels in innovative infrastructure management. We've employed subsurface mapping for underground insights, used AR and GPR for bridge inspections, and harnessed drones with AR for building assessments. We've also advanced in water pipeline monitoring, pavement crack detection, and ensured construction quality through lift-thickness and compaction monitoring. These efforts position us at the forefront of infrastructure technology.
